<p>It's not a problem to me. I just want to offer a true information, tested... Additionally, and another topic... I was trying a lot of possibiliies to get the best performance possible... One was transcode option to replace media in video. One of them, was a movil (cellphone) video ( <span>720x1440) </span>, it was transcoded adding black bands to complete 16:9 aspect, 1920x1080. </p>

<p>Phyllis, Yes! just this parameter, but if you want, give me a few day to more test. At this moment.. rendering 4minutes x 30 fps, full-hd, with masks, 11.685fps, rendering same time with constant zoom and chromakey, 9.04 fps. The detail is,before was rendering a 6 fps.</p>
<p>I want to test little more to confirm stability, HW rendering I can confirm now.</p>

<div class="gmail_default" style="font-size:small">Thank you so much for sharing your results which are quite impressive. Am I understanding correctly that the only change you ended up making was the"<span><strong>hwaccel_flags to (0x00000002) ?? </strong>allow_high_depth" to the h264-nvenc.mp4 ffmpeg option file? I want to add that as a choice for others to see. Probably your newer/higher end graphics board was very beneficial -- a good way to justify upgrading if using h264/h265.<br> </span></div>

<p>Thanks a lot! Well...</p>
<p>pipe option isn't better in this case (I did some test). Changing <span> parameters to pass in the "view" button, ffmpeg option, not codec, is better. Attached images show some information to think it's using HW Acceleration. It's using 2 of 6 cores when before used all cores to reender. And use dedicate memory of graphic card and more GPU and video engine. Render time reduce about 25% and that's excelent </span></p>

<p>Oh! The more important topic ! Manual is amazing. I'm trying to translate to spanish (slowly) to read the whole book and colaborate with CinGG</p>

<p>My original question was: Can I pass some imput parameters to ffmpeg in render process? And I ask this again. Why? Becase <span>ffmpeg </span><span>-hwaccel cuvid can enconder x264 at 13,7x and without this parameter, just 2.5x. And at the moment, x264 is sufficient for me.</span></p>

<div><span class="gmail_default" style="font-size:small">One way to get parameters passed to ffmpeg while rendering is using the "Piping Video to a Command Line" (this was adapted from CV) and is documented in Rendering chapter 6 of the manual (6.5.6 section). I have not re-tested that in awhile but there is no reason that it should not be working.</span></div>
<div><span class="gmail_default" style="font-size:small"> </span></div>
<div><span class="gmail_default" style="font-size:small">The second way which might only work for certain parameters, is to click on the Video wrench in the Render Menu and try to see if the parameter you want to pass is available in either the "view" button which brings up another menu and on the top right hand side is the button "Kind" which defaults to "codec" but can be set to "ffmpeg". And/Or click on the "format" button which provides additional parameters -- these only sort of work and probably not what you want.<br> </span></div>
<div><span class="gmail_default" style="font-size:small"> </span></div>
<div><span class="gmail_default" style="font-size:small">A third way is just to write a Shell Command and use that via the "shell cmds" button in the upper right hand corner of the timeline by the "Ffmpeg use first/last button".<br> </span></div>
